A 50 watt panel seems more practical for cruising. On my boat I think I'd charge it off an echo charger, then it could also be charged from the sailboat's alternator. This is sounding like a pretty good alternative to my 2hp Honda (which I have to run pretty close to idle speeds anyway). What does a salt water rated electric outboard cost?
The salt water motor is about $300.
At $99 the motor pretty much becomes a throw away, I've put more $$ than that into parts for the #$%@$% 3.5hp 2 stroke Tohatsu this season already.
The way I'm looking at is electric motors are improving by leaps and bounds. If I can get three seasons of light use out of the little sucker I'm ahead of the game and there will be something better/cheaper on the market when I'm ready to replace it.
I called Dick's today and they have one in stock. $15 more than Amazon but I can pick it up tonight and no shipping costs.
